Description

Technical Field

[0001] This application relates to the field of battery technology, and in particular to a baffle assembly, a coating apparatus, and a coating transfer device. Background Technology

[0002] Transfer coating is a coating technology typically used to apply a uniform coating to the surface of a substrate. This method involves first applying the coating to an intermediate carrier (such as a coating roller or coating belt) and then transferring the coating from the intermediate carrier to the target substrate. This technology can be used for a wide variety of materials and applications, including paper, textiles, plastic films, and metal foils.

[0003] Taking a lithium battery, which requires coating, as an example, a blank area for the tabs in the center of the lithium battery is typically required. In related technologies, when manufacturing an intermediate carrier such as a coating roller, a blank area is usually etched onto the coating roller to form an anilox roller, based on the size of the tabs in the center of the lithium battery. Transfer coating is then achieved using the material storage function of the anilox roller. Specifically, areas on the anilox roller without the anilox pattern will not have coating material, thus creating a blank area on the target substrate.

[0004] However, the above solution requires different anilox rollers to be used for target substrates with different blanking requirements, which is too costly. Utility Model Content

[0007] The first surface of the baffle body is smooth, and the second surface of the baffle body has a plurality of protrusions arranged in an array.

[0008] This application's embodiments, through the design of a baffle assembly, prevent slurry transfer during transfer coating of the target substrate. Consequently, the area corresponding to the baffle assembly remains blank, achieving a white space. By adjusting the shape and number of the baffle assemblies, different white space requirements can be met. Furthermore, the baffle assembly is designed with one side smooth and the other side having multiple arrayed protrusions. From a contact principle perspective, these protrusions reduce friction and prevent slurry carryover, effectively buffering the slurry. Therefore, compared to related technologies, this application eliminates the need to change coating rollers when coating target substrates with different white space requirements, resulting in cost savings.

[0009] In one possible implementation, the cross-sectional area of ​​the protrusion gradually decreases from one end closer to the baffle body to the end farther away from the baffle body.

[0023] In one possible implementation, the support assembly includes: a support body and a support arm;

[0024] The support body is located on the side of the discharge assembly away from the coating roller. One end of the support arm is connected to the support body, and the other end of the support arm extends around the discharge assembly to the coating roller.

[0025] At least one end of the baffle assembly is connected to the end of the support arm that is away from the support body.

[0026] In one possible implementation, the number of support arms is one;

[0027] One end of the baffle assembly is connected to the end of the support body opposite to the support arm, and the other end of the baffle assembly is connected to the end of the support arm opposite to the support body. At least a portion of the baffle assembly is fixed to the coating roller.

[0069] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0070] With the development of new energy sources, more and more fields are adopting new energy sources as power sources. Due to their advantages such as high energy density, rechargeability, safety, and environmental friendliness, batteries are widely used in new energy vehicles, consumer electronics, energy storage systems, and other fields.

[0071] Batteries are a core component of new energy vehicles, and their safety directly affects the overall safety performance of the vehicle.

[0072] For lithium batteries requiring coating, a blank area for the tabs in the center of the battery is typically left blank. In related technologies, when manufacturing the coating roller, a blank area is usually etched onto the roller to form an anilox roller, based on the size of the tabs in the center of the lithium battery. The material storage function of the anilox roller is then used to achieve transfer coating. Specifically, areas on the anilox roller without the anilox pattern will not have coating, thus creating a blank area on the target substrate.

[0073] However, different anilox rollers are required for different target substrates with different blanking requirements, which is too costly.

[0074] To address the aforementioned problems, this application provides a novel baffle assembly, coating apparatus, and coating transfer device. The baffle assembly includes a baffle body having opposing first and second surfaces. The first surface of the baffle body is smooth, and the second surface has a plurality of arrayed protrusions. This application can save costs when coating target substrates with different blanking requirements.

[0075] The following detailed description, in conjunction with the accompanying drawings, describes the baffle assembly, coating apparatus, and coating transfer device provided in the embodiments of this application.

[0076] Figure 1 This is a schematic diagram of a baffle assembly provided in an embodiment of this application. Figure 2 This is a schematic diagram of another structure of the baffle assembly provided in an embodiment of this application.

[0077] Reference Figure 1 and Figure 2 As shown, this application embodiment provides a baffle assembly 100, which may include a baffle body 110, the baffle body 110 having a first surface 1101 and a second surface 1102 opposite to each other, wherein the first surface 1101 of the baffle body 110 may be smooth, and the second surface 1102 of the baffle body 110 may have a plurality of protrusions 111 arranged in an array.

[0078] By designing the baffle assembly 100, when the target substrate is being transferred and coated, the baffle assembly 100 prevents the slurry from transferring, so that the area corresponding to the baffle assembly 100 is free of slurry, thus achieving blanking. By adjusting the shape and number of the baffle assembly 100, different blanking requirements can be met.

[0079] In addition, the baffle assembly 100 is designed such that one side of the baffle body 110 is smooth and the other side has multiple arrayed protrusions 111. Thus, from the perspective of contact principle analysis, the protrusions 111 have less friction and will not carry material, and can play the role of buffering slurry.

[0080] Therefore, compared with related technologies, when coating target substrates with different blanking requirements, this application does not require changing different coating rollers, which can save costs.

[0081] In this embodiment, the cross-sectional area of ​​the protruding structure 111 can gradually decrease from one end near the baffle body 110 to the other end away from the baffle body 110.

[0082] In the embodiments of this application, the cross-sectional shape of the protrusion structure 111 is rectangular, triangular or circular, etc. The embodiments of this application do not limit this, nor are they limited to the above examples.

[0083] In other words, in this embodiment of the application, the shape of the protrusion structure 111 can be pyramidal, conical, or other conical, and this embodiment of the application does not limit this.

[0084] From the perspective of contact principle analysis, the raised structure 111 reduces friction, buffers the slurry, and allows it to flow. Furthermore, the size of the raised structure 111 can be adapted to 200-line, 300-line, or 400-line textures.

[0085] For example, in some application scenarios, the side length of the protrusion 111 can be 1.7 mm, and the height of the protrusion 111 can be 0.3 mm. It should be noted that the size of the protrusion 111 can be flexibly designed according to the needs of the actual application scenario, and the embodiments of this application do not limit it, nor are they limited to the above examples.

[0086] In this embodiment, the baffle assembly 100 may be made of silicone or rubber, etc. Silicone and rubber are soft and wear-resistant.

[0087] In this way, the baffle assembly 100 has high flexibility and high wear resistance. One side of the baffle assembly 100 is provided with a raised structure 111. After experimentation, the blank space in the middle has no scratches, no material sticking or adhering, and can achieve the expected function.

[0088] In this embodiment of the application, the thickness of the baffle assembly 100 can be 0.3mm-1.0mm. Exemplarily, the thickness of the baffle assembly 100 can be 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm or 1.0mm, etc., and this embodiment of the application does not limit it, nor is it limited to the above examples.

[0089] It should be noted that the numerical values ​​and ranges involved in this application are approximate values. Due to the influence of the manufacturing process, there may be a certain range of errors, which can be considered negligible by those skilled in the art.

[0090] Figure 3 This is a schematic diagram of the coating apparatus provided in an embodiment of this application. Figure 4 This is a schematic diagram of the structure of the support component and the baffle assembly 100 in the coating apparatus provided in the embodiments of this application.

[0091] This application also provides a coating apparatus 200, see reference. Figure 3 and Figure 4 As shown, the coating apparatus 200 may include a coating roller 210 and the aforementioned baffle assembly 100, wherein at least a portion of the baffle assembly 100 may cover the coating roller 210. Specifically, in this embodiment, the protrusion 111 on the baffle assembly 100 may face the coating roller 210, and the protrusion 111 will not accumulate material.

[0092] By providing the baffle assembly 100 in the coating apparatus 200, it is not necessary to change different coating rollers 210 when coating target substrates with different whiteness requirements, which can save costs.

[0093] In this embodiment of the application, the coating apparatus 200 may further include a discharge assembly 220, wherein the discharge port 221 of the discharge assembly 220 may be disposed opposite to the coating roller 210.

[0094] In this embodiment of the application, the discharge component 220 may include a discharge trough 222 and a scraper 223, wherein the scraper 223 may be connected to the discharge trough 222.

[0095] In this embodiment of the application, the number of scrapers 223 can be one or more. For example... Figure 3 As shown, the number of scrapers 223 is one. Of course, in some other embodiments, the number of scrapers 223 may be one, three, four, five, six or more. This application embodiment does not limit this, nor is it limited to the above example.

[0096] Continue to refer to Figure 3 As shown in the embodiment of this application, the discharge port 221 can be disposed on the side of the discharge trough 222 facing the coating roller 210, and the scraper 223 can be located between the discharge port 221 and the coating roller 210.

[0097] Moreover, in one possible implementation, the extension direction of the doctor blade 223 can be tangent to the rotation direction of the coating roller 210.

[0098] In this embodiment of the application, the discharge assembly 220 may further include a fixing plate 224, wherein one side of the scraper 223 may be connected to the discharge trough 222, and the other side of the scraper 223 may be connected to the fixing plate 224.

[0099] In some embodiments, see Figure 3 As shown, the fixing plate 224 and the discharge trough 222 are connected by a third fixing member 270, thereby connecting the scraper 223 and the discharge trough 222.

[0100] In this embodiment of the application, the discharge assembly 220 may further include a feed inlet 225, wherein the feed inlet 225 may be disposed on one side of the discharge trough 222 located on the coating roller 210.

[0101] See Figure 3 and Figure 4 As shown in the embodiments of this application, the coating apparatus 200 may further include a support component 230, wherein at least a portion of the support component 230 may be located on the side of the discharge component 220 away from the coating roller 210.

[0102] In this embodiment of the application, one end of the baffle assembly 100 can be connected to one end of the support assembly 230, and the other end of the baffle assembly 100 can be connected to the other end of the support assembly 230.

[0103] Specifically, in this embodiment, the support component 230 may include a support body 231 and a support arm 232. The support body 231 may be located on the side of the discharge component 220 away from the coating roller 210. One end of the support arm 232 may be connected to the support body 231, and the other end of the support arm 232 may extend around the discharge component 220 to the coating roller 210. In addition, at least one end of the baffle component 100 may be connected to the end of the support arm 232 away from the support body 231.

[0104] It should be noted that, in the embodiments of this application, the specific configuration of the support arm 232 may include, but is not limited to, the following two possible implementation methods:

[0105] One possible implementation is that there is one support arm 232. In this case, one end of the baffle assembly 100 can be connected to the end of the support body 231 away from the support arm 232, and the other end of the baffle assembly 100 can be connected to the end of the support arm 232 away from the support body 231. Moreover, at least a portion of the baffle assembly 100 can be fixed to the coating roller 210.

[0106] Another possible implementation is that there are two support arms 232. In this case, one end of the baffle assembly 100 can be connected to one of the two support arms 232, the other end of the baffle assembly 100 can be connected to the other of the two support arms 232, and at least a portion of the baffle assembly 100 can be fixed to the coating roller 210.

[0107] It should be noted that in this embodiment, the less contact surface between the baffle assembly 100 and the coating roller 210, the better. By extending or shortening the support arm 232, the contact between the baffle assembly 100 and the coating roller 210 can be adjusted to be point contact.

[0108] Additionally, it is understood that in this embodiment, each support arm 232 may be provided with a clamping member 233 at one end away from the support body 231. The clamping member 233 is used to clamp the baffle assembly 100 so as to connect the baffle assembly 100 with the support arm 232.

[0109] It is understood that in some embodiments, the clamping member 233 may be fixed to the end of the support arm 232 away from the support body 231 by the first fixing member 250.

[0110] Specifically, such as Figure 4 As shown, the clamping member 233 may include a first clamping part 2331 and a second clamping part 2332. The end of the baffle assembly 100 may be located between the first clamping part 2331 and the second clamping part 2332. The first clamping part 2331 and the second clamping part 2332 may be fixed together by a second fastener 260, thereby achieving clamping of the baffle assembly 100.

[0111] It is understandable that, in one possible implementation, such as Figure 4 As shown, the first clamping part 2331 can be a screw, and the first clamping part 2331 is fixed to the end of the support arm 232 away from the support body 231 by the first fixing member 250. The second clamping part 2332 can be a locking piece, and the second clamping part 2332 can be fixed to the first clamping part 2331 by the second fixing member 260.

[0112] In addition, in this embodiment of the application, the coating apparatus 200 may also include a support member 240, which may be located below the baffle assembly 100 and between the first clamping part 2331 and the second clamping part 2332 to support the baffle assembly 100.

[0113] It should be noted that the support member 240 is movable and has no actual connection with the baffle assembly 100 or the clamping member 233.

[0114] Figure 5 This is a schematic diagram of a coating transfer device provided in an embodiment of this application. Figure 6 This is another structural schematic diagram of the coating transfer device provided in the embodiments of this application.

[0115] This application also provides a coating transfer device 300, see reference. Figure 5 and Figure 6As shown, the coating transfer device 300 may include a coating device 310 and the coating device 200 described above, wherein the coating device 200 may be used to coat the component 312 to be coated in the coating device 310.

[0116] By installing the coating device 200 in the coating transfer equipment 300, it is not necessary to change different coating rollers 210 when coating target substrates with different white space requirements, which can save costs.

[0117] In this embodiment of the application, the coating device 310 may include a conveying component 311 and a coating component 312, wherein at least a portion of the coating component 312 may be disposed on the conveying component 311, and the conveying component 311 is used to convey the coating component 312.

[0118] In this embodiment, in the working mode, the coating apparatus 200 has the discharge assembly 220 moving towards the coating roller 210. The scraper 223 of the discharge assembly 220 adheres to the coating roller 210 to scrape off excess slurry. The discharge port 221 of the discharge assembly 220 feeds the coating roller 210, which then transfers the slurry onto the coating assembly 312, achieving a transfer coating.

[0119] Due to the presence of the baffle assembly 100, during transfer coating, the baffle assembly 100 prevents the slurry from transferring, thus ensuring that the area corresponding to the baffle assembly 100 on the component 312 to be coated is free of slurry coating, achieving a blank space. The position, shape, and number of the baffle assembly 100 can be adaptively adjusted according to different blank space requirements, offering good versatility and ease of implementation.
